Title: Protection device of turbosupercharger type diesel engine
Inventor: MIURA SANEHIRO
IPC: F02B37/00
Filed: 1982-01-19
Abstract: PURPOSE:To prevent the vibrations and noises of the titled engine when the engine is idling or stopped and to protect the engine at the time when the air sucking pressure of the engine rises too high by a method wherein when it is detected that the pressure in the air sucking pipe exceeds a predetermined value due to the pressure of supercharged air, an air sucking pipe throttle valve is driven at its intermediate position. CONSTITUTION:In case where the engine is operated at low temperatures without the necessity of increasing the fuel quantity or in case where the engine is in a no load operation condition without the necessity of stepping on the acceleration pedal, an acceleration switch 28 is closed and a relay switch 27 is opened to keep a negative pressure changeover valve 13 deenergized so that a port A is made to communicate with a port B and a negative pressure is introduced into a first diaphragm chamber 8. Accordingly, a butterfly valve 3 shifts to its intermediate position shown by a hypothetical line 1 and sucked air is choked by the valve in that condition. In this case, as the engine is in a no load operation condition, the number of revolutions of the engine is small and further, in the case of the instant engine which has a high compression efficiency, it is possible to prevent the compression force of the engine from increasing excessively by choking the sucked air to about 10-30%, to thereby reduce the vibrations and noises of the engine.

Title: Tape carrier for double-side protective coat type tab
Inventor: ONDA MAMORU
IPC: H01L21/60
Filed: 1989-01-12
Abstract: PURPOSE:To reduce the warpage of a film, and to improve yield by forming protective coats onto both the surface and the rear except the soldering sections of an inner lead and an outer lead. CONSTITUTION:A protective coat 2 is executed to the surface (a section surrounded by a dotted line) except the inner lead sections 7 of a tape for a TAB(Tape Automated Bonding) and the sections of outer leads 6 soldered, and the same protective coat 2 is executed onto the rear oppositely faced to the surface coat area. It is favorable that the protective coat 2 is formed through a screen printing method by using a solder resist ink, but an organic insulating compound such as epoxy paints or a material, in which an inorganic group insulating compound is mixed with the organic insulating compound, has the advantage of fine pattern printing properties (the control of the fluidity of ink). Accordingly, the yield of the nondefectives of element junctions is improved, and production cost can be reduced largely.

Title: Dependent synchronous switching control system
Inventor: KATAGIRI MAKIO
IPC: H04B7/19
Filed: 1990-01-17
Abstract: PURPOSE:To achieve clock network synchronization at low cost while maintaining sufficient reliability by operating a satellite line dependently in synchronizing to a master clock on a ground network side, and maintaining the operation by using a clock on a satellite line side when a fault is generated at the ground line. CONSTITUTION:When a ground line 2, to which a both station multiplexers MUX 1 is connected, is normal, a satellite line 21 establishes clock network synchronization dependent to this satellite line with the ground network clock as a reference, and when the fault is generated only at the MUX connecting ground line of one side station, the clock network synchronization is established while making the satellite line clock dependent to the ground network clock to be supplied from one normal station side. When the faults are successively generated at the MUX connecting ground lines of the both stations with time difference >= about 0.26sec., a reference clock in satellite terminal station is defined as the master clock and the MUX 1 of the both stations and a satellite terminal station 12 establish the clock network synchronization dependent synchronously to this master clock. Thus, when a ground digital line network 2 and an independent digital satellite line 21 are used, the clock network synchronization in a system can be established at low cost with sufficient reliability.
